Series 909QT: This valve incorporates the (“air-in/water-out”) principle which substantially improves the relief valve discharge performance. (The emergencyconditions of combined back siphonage and back pressure with both checks fouled can defeat the effectiveness of a standard RPZ backflow preventers).
DELAY MY SHIPMENT until all in-stock items AND backordered items are available in one warehouse before shipping. (You will receive only one freight bill if you choose this option).
